摘要

This paper presents the design of an endoscopic clip with a battery-less LED for laparoscopic gastrointestinal resection. A radio wave from an electric scalpel is utilized as a source for LED illuminating. In order to translate the radio wave to DC voltage, a series LC circuit and a Cockcroft-Walton circuit are combined as a test circuit. The size of the final circuit is 1.8 mm in width and 12 mm in length, therefore our proposed circuit is able to be placed in the body through an endoscope.
